will propose to discuss an open problem: "how to prove Fourier
law with a deterministic model?". Is it possible to use recent
technics in hyperbolic dynamics (central limit theorem, exponential
decay of correlations etc)?

III: Fast-slow partially
hyperbolic systems versus Freidlin-Wentzell random systems : We
consider a simple class of fast-slow partially hyperbolic dynamical
systems and show that the (properly rescaled) behaviour of the slow
variable is very close to a Friedlin--Wentzell type random system for
times that are rather long, but much shorter than the metastability
scale. Also, we show the possibility of a "sink" with all the Lyapunov
exponents positive, a phenomenon that turns out to be related to the
lack of absolutely continuity of the central foliation.

Since the train station is 30mn from Peyresq
by car, it is better if you can arrive simultaneously on Sunday 4th june:
I propose to take the train in Nice a 17h15 -> Meailles
19h20

(or the one before: Nice 13h05 -> Meailles 15h01 but i am not
sure to be able to be there)

Then a car (or some cars) will take you in Meailles to Peyresq.

An other possibility for people who like walking on a
nice small path in the mountain , with a backpack (no
suitcase): stop at the train station called "arrêt de Peyresq" (you
have to ask to the train driver) and follow the
path
on this map that goes to the north. You start above and
along the right side of the river "Vaïre". After walking flat
2km, you arrive at the ruins of Moulin du Ray", then the path goes up.
You will have 500 meters elevation, may be 2h.

For people coming from grenoble:

We will
have a minibus with 9 places starting
from Grenoble. So you can join us in Grenoble. We will start around 13h from
grenoble, train station, side of "palais de justice", so that we can wait
the train Paris 9h45 -> Grenoble 12h46. If the weather is
good, we will buy a picnic in grenoble and take the lunch on the
road.

Other activities

Look at mountain
flowers. This will the full season of blowing flowers. Here is a list
or here. Make a tour around
Peyresq and try to recognize them!

Walk in the moutain around
Peyresq. Bring good clothes and shoes. Here is a
map . There is a local summit (2693m = Peyresq + 1170m): "le
grand coyer" and a more local one (2157m = Peyresq + 620m) "le
courradour". There is a
small cave to visit, bring your lights. La
grotte de Meailles
